Rice Lake, Wisconsin, located in the Northern Temperate Zone, presents a mixed picture for year-round solar energy generation. This location experiences significant seasonal variations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems throughout the year.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Rice Lake, with an impressive daily output of 6.54 kWh per kW of installed solar capacity. Spring follows as the second-best season, generating 5.15 kWh/day. However, the colder months see a substantial drop in production, with autumn yielding 3.18 kWh/day and winter plummeting to a mere 2.15 kWh/day.

These figures highlight the stark contrast between the warm and cold seasons, with summer producing more than three times the energy of winter. This disparity underscores the challenges of relying solely on solar power year-round in Rice Lake.

Optimal Panel Installation

To maximize year-round solar production in Rice Lake, fixed panels should be installed at a tilt angle of 39 degrees facing south. This angle is calculated to capture the most sunlight throughout the year, considering the location's latitude and seasonal sun positions.

Environmental and Weather Factors

Several factors can impede solar production in Rice Lake: 1. Snowfall: Winter accumulation can cover panels, reducing efficiency. 2. Cloud cover: The region experiences frequent overcast days, especially in winter.

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off. Regular panel cleaning and the use of snow-shedding technologies can also help maintain efficiency during winter months. Additionally, investing in high-efficiency panels can help maximize production during periods of reduced sunlight.

Conclusion

While Rice Lake's location is not ideal for year-round solar energy production, it still offers significant potential, especially from spring through fall. With proper installation techniques and maintenance practices, solar PV systems can provide a valuable source of renewable energy for this Wisconsin community.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Rice Lake

Seasonal solar PV output for Latitude: 45.5055, Longitude: -91.7312 (Rice Lake, United States), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 39° South in Rice Lake, United States

To maximize your solar PV system's energy output in Rice Lake, United States (Lat/Long 45.5055, -91.7312) throughout the year, you should tilt your panels at an angle of 39° South for fixed panel installations.

As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.

We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Rice Lake, United States

If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Rice Lake, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
29° South in Summer	49° South in Autumn	59° South in Winter	39° South in Spring

Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.

This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Calculate solar panel row spacing in Rice Lake, United States

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Rice Lake, United States.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. Minimum Spacing:
   We add the shadow length to the horizontal space occupied by tilted panels.

This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.

Topography for solar PV around Rice Lake, United States

The area surrounding Rice Lake, located in northwestern Wisconsin, United States, is characterized by a diverse and gently rolling topography. This region, part of the Northern Highland geographic province, features a landscape shaped by glacial activity during the last ice age. The terrain consists of a mix of low hills, shallow valleys, and numerous small lakes and wetlands. Rice Lake itself sits at an elevation of around 1,140 feet (347 meters) above sea level. The surrounding area gradually rises and falls, with elevations typically ranging from 1,100 to 1,300 feet (335 to 396 meters). The landscape is dotted with forests, primarily composed of mixed hardwoods and conifers, interspersed with open fields and agricultural land.

Nearby Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Rice Lake, several factors come into play. Ideal sites would have relatively flat or gently sloping terrain, minimal shading from trees or structures, and good access to existing electrical infrastructure. The agricultural areas to the south and southeast of Rice Lake present promising opportunities for solar PV development. These regions feature more open, cleared land with fewer obstructions that could cast shadows on solar panels. The gently rolling terrain in these areas would allow for efficient panel placement without significant earthwork. Another potentially suitable area lies to the northwest of Rice Lake, where there are expanses of relatively flat land interspersed with forested patches. While some clearing might be necessary, these areas offer a good balance of open space and proximity to existing infrastructure. It's important to note that while the topography around Rice Lake is generally favorable for solar PV installations, site-specific assessments would be necessary to determine the most suitable locations. Factors such as soil conditions, drainage patterns, and local zoning regulations would also need to be considered in addition to the topographical features.

United States solar PV Stats as a country

United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in United States?

Yes, there are several incentives for businesses wanting to install solar energy in the United States. These include federal tax credits, state and local rebates, net metering policies, and renewable energy certificates (RECs). Additionally, many states have enacted legislation that requires utilities to purchase a certain amount of electricity from renewable sources such as solar.
